So the greatest common factor 1581,1290 is 3.
Lets's calculate LCM of 956,1627
Given numbers has no common factors except 1. So, there LCM is their product i.e 1555412
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/1555412
Therefore, the GCF of Fractions 1581/956,1290/1627 is 3/1555412
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 956,1627 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(956,1627) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(956,1627) x common factors =1 x 1 = 1
LCM(956,1627) = ( 956 × 1627 ) / 1
LCM(956,1627) = 1555412 / 1
LCM(956,1627) = 1555412
